How To Detect Diesel Generator Set Failure By Test Temperature

Temperature detection is an important means of fault detection of diesel generator set. By monitoring the temperature of some components or systems, faults can be found and repaired in time to ensure the normal operation of diesel generator set. The following will describe in detail how to detect the fault of the diesel generator set through the test temperature.
First, determine the detection object and detection point
First of all, we must determine the components and systems that need to be tested. Conventional test points include: engine, generator, lubricating oil, cooling water, fuel, etc. For the engine, the temperature of the cylinder block, water tank, exhaust pipe, oil pan and other components can be detected; For generators, the temperature of bearings, stators, rotors and other components can be detected; For lubricating oil and cooling water, the temperature at the inlet and outlet can be detected; For fuel, the temperature before it enters the engine can be detected.
Second, choose the right temperature detection instrument
According to different detection objects and detection points, choose the appropriate temperature detection instrument. Commonly used temperature measuring instruments include: infrared thermometer, thermocouple, thermal resistance and so on. For different detection objects and detection points, different instruments can be selected for measurement to ensure the accuracy and reliability of the measurement results.
Three, temperature measurement
Use the selected temperature measuring instrument to measure the temperature of the test object and test point. Before measurement, the instrument should be calibrated to ensure accurate and reliable measurement results. In the measurement process, it is necessary to pay attention to the position and direction of the measuring instrument to ensure that the measuring point can be accurately detected, and it is also necessary to pay attention to the impact of the measuring environment, such as wind direction, light and other factors will affect the measurement results, and the corresponding compensation is required.
4. Analyze and solve problems
After the temperature measurement is completed, the measurement results need to be analyzed, according to the measurement results to determine whether there is a fault, and the corresponding maintenance. For example, if the engine block temperature is too high, there may be poor cylinder seal, cooling system failure and other problems; If the generator bearing temperature is too high, there may be poor lubrication, bearing wear and other problems. According to the specific situation, analyze the fault and take the corresponding maintenance and adjustment measures.
5. Record and organize
In the process of temperature detection, the measurement results and analysis conclusions should be recorded in time, and sorted into the corresponding report. These records and reports are very important for subsequent maintenance work and can provide a reference for future maintenance, but also help to monitor and evaluate the performance and operating status of the diesel generator set.
In short, the fault of the diesel generator set can be found in time through temperature detection, which helps to ensure its normal operation and extend its service life. Before the temperature detection, it is necessary to select the appropriate detection object and detection point, select the appropriate temperature detection instrument, accurate and reliable temperature measurement, and analyze and solve the problem according to the measurement results.
